Abstract

By finding a parabola solution connecting two equilibrium points of a planar dynamical system, the existence of the kink wave solution for 6 classes of nonlinear wave equations is shown. Some exact explicit parametric representations of kink wave solutions are given. Explicit parameter conditions to guarantee the existence of kink wave solutions are determined.

Key words： kink wave solution; connecting orbit; parabola solution; nonlinear wave equation; nonlinear evolution equation
